hardware hacking--I saw instructions for soldering--in order to hook up a
modem to a cell phone. I'm not entirely sure I understand the purpose
or feasibility of this hack, but the comments are interesting.<br>http://everything2.com/title/How+to+connect+any+cellular+phone+to+a+modem<br><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: arial,helvetica,sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: arial,helvetica,sans-serif; background-color: transparent; font-style: normal;"><br></div><div style="color: rgb(0, 0, 0); font-size: 13.3333px; font-family: arial,helvetica,sans-serif; background-color: transparent; font-style: normal;">Anyway, <span>here are some notes and links I have gathered. This is not an easy subject to look up as most of the time, the conversation and instructions are about mobile tethering and 3G modems. Also a lot of the relevant conversation for dialing out to other modems tends to be from 2007 and earlier, back when the desire was more common.

<br>Hi folks,<br><br>So as you know I've put up a BBS (626-441-2970), but it seems that most<br>people no longer have access to the technology needed to access it. Very<br>sad.<br><br>So I'd like to challenge the group to find a solution. Can you dial in at<br>300 baud over a cell phone? Or without a modem?<br><br>This could be a real public service for, for example, political dissidents<br>when a nation's broadband goes dark. And it sounds like fun.<br><br>-braddock<br><br> ____ __ <br> / __ \ ____ _ _____ ____ / /_ ___ _____ _____ __ __<br> / /_/ // __ `// ___// __ \ / __ \ / _ \ / ___// ___// / / /<br> / _, _// /_/ /(__ )/ /_/ // /_/ // __// / / / / /_/ / <br>/_/ |_|
